1. |4×|=2×+12 2. |4×-16|=2×-10 cari himpunan!

1. => 4x = 2x+12
4x-2x=12
2x=12
x=6
=>4x= - (2x+12)
4x= -2x-12
4x+2x= -12
6x= -12
x= -2
jadi , HP = { -2,6}

1. |4x| = 2x + 12
=> 2x + 12 = +- 4x
=> 2x + 12 = 4x
= 2x - 4x = -12
= -2x = -12
= x = 6
=> 2x + 12 = -4x
= 2x + 4x = -12
= 6x = -12
= x = -2
Hp { -2,6}
2. |4x - 16| = 2x -10
=> 2x - 10 = +- ( 4x - 16)
= 2x - 10 = 4x - 16
= 2x - 4x = -16 + 10
= -2x = -6
= x = 3
=> 2x - 10 = -4x + 16
= 2x + 4x = 16 + 10
= 6x = 26
x = 26/6
x = 13/3

Hp { kosong }
karena x kurang dari 4
